Mary Abercromby, 1st Baroness Abercromby

Mary Anne Abercromby, 1st Baroness Abercromby (née Menzies, born before 1752 – 11 February 1821) was a Scottish socialite and suo jure peeress.

Mary Anne was the daughter of John Menzies and Ann, daughter of Patrick Campbell. She was created suo jure 1st Baroness Abercromby, of Aboukir and of Tullibody, in the County of Clackmannanshire, by Letters Patent on 28 May 1801. The barony was awarded in recognition of her late husband's gallantry at the Battle of Alexandria, at which he was mortally wounded. On her death in 1821 she was succeeded in the barony by George, her eldest son.

She married Captain Ralph Abercromby (later Lt.-Gen. Sir Ralph Abercromby), son of George Abercromby and Mary Dundas, on 17 November 1767. They had children:

• Hon. Anne Abercromby (died 1844)
• Hon. Mary Abercromby (died 1825)
• Hon. Catherine Abercromby (died 1841)
• George Abercromby, 2nd Baron Abercromby (1770–1843)
• Gen. Hon. Sir John Abercromby (1772–1817)
